COIN-OPERATED STEREOSCOPE.

SPECIFICATION forming part of Letters Patent No. 405,321, dated J une18, 1889.

Application led February 10, 1888. Serial No.. 263,607. (No model.)

To all whom t may concern.'

Be it known that I, CLARA E. PATTERSON, of the city, county, and Stateof New York, have invented an Improvement in Coin- Operated LockingDevices for Stereoscopes an d Similar Apparatus, of which the followingis a specification.

My invention has reference to coin-operated devices for stereoscopes andsimilar apparatus; and it consists of certain improvements which arefully set forth in the following specication and shown in theaccompanying drawings, which form part thereof.

While my invention has particular bearing upon stereoscopes as knowninthe market, it is understood that it is adapted to any and all devicesin which a handle 'is to be rotated by the person who is to receive anequivalent for the money deposited. The essential features, broadlyconsidered, may be enumerated as a handle to operate something, which ina stereoscope is a chain of pictures, a locking device, substantiallysuch as hereinafter set out, to prevent the rotation of themechanismoperated by the handle except when a coin is deposited, anddevices Clescribed later on to automatically relock the mechanism afterit has been given a predetermined number of movements by the handle.

To prevent the cheating of the machine by the deposit of buttons andother articles not legal tender, I employ a push-pin which forciblypushes the coin between sliding bolts, whereby the power of the hand canput the lock out of action, and the size and strength of the coin,rather than its weight, are employed to insure the unlocking of thedevices for operation.

In the drawings, Figure l is a front elevation of a stereoscope andlocking device embodying the principles of my invention, having aportion of its outer casing or box removed. Fig. 2 is a side elevationof the same. Fig. 3 is a plan view of the coin-operated mechanism. Fig.4 is a sectional viewof the coin-guide and push-pin to one side of theline of Fig. 5, which is a Vcross-sectional view through the line y f l/of Fig. 4. Fig. 6 is a perspective view of the mechanism operated by thccoin detached from the case, and

less chain or band guided upon a drum D.

The drum D is preferably square, and is rofated by a shaft d, to whichit is attached, and which terminates in a handle E on the outside of thebox. Each of the picture-holders C (of which there may be any numberdesired) is provided with a picture c, which are successively presentedbefore the sight-aper ture B upon rotating the drum D by means of thehandle E. Normally, however, the drum D and endless chain cannot berotated by the handle E because of the locking devices, hereinafterdescribed, and it is not until a coin has been deposited in the box thatthe mechanism can be unlocked and the drum and endless chain rotated bythe handle E.

F is aratchet-wheel secured to the drum D and upon its shaft d, and f isa locking-pawl therefor to prevent backward movement.

G are spur-gearing meshing together, one of which is mounted on thedrum-shaftd and the other upon the shaft H. This shaft I- I is locatedwit-hin the frame of the box, j ournaled in a support or frameworkWithin it, and is provided with a pin or projection h, which is adaptedto be engaged by a locking-bolt.

K is the locking-bolt, supported in any suitable manner within the box4and having a beveled or tapering end la. This locking-boltK has anangular end K', which is normally adapted to rest. against theprojection h on the shaft H. K2 is a rod or bolt similarly provided witha tapering end 7c. These two bolts K and K2 are loosely supported intheir frames, so asv to admit of lateral reciprocation.

L L are springs to normally keep the bolts in place with their beveledends k k at a given distance from each other.

M is a latch-hook pivoted by a pin to the box A or otherwise, asdesired, and is adapted to catch the end K when it is forced beneath it.This latclbhook M is provided withan IOO arm m, extending from its sideand adapted to be struck and lifted by a pin N upon the shaft H.

J is a push-pin having a spring j and located in the box A in front ofthe bolts K and K2 and between their beveled ends L k.

I is the coin-guide tube, having a slot or coin-aperture 'z'. to receivethe coin of the exact size. This tube I extends downward through the boxA, and is provided with openings through which the tapered ends 7c k ofthe bolts K and K2 and the end of the push-pin J may enter. At thispoint it preferably has a slight bend or elbow.

In operation the coin is dropped through the aperture fz, and, fallingthrough the tube I, is caughtbetween theends 7i'. 71; of the bolts K andIYQ upon the elbow or bend in the tube. If the pin J is now pushed in,the coin will be forced between these ends 7.: k', which will thus beforced apart. rlhis will push the end K away from the projection h. Thelatchliool( M now catches the end K and'holds the bolt K back. Thehandle E may then be rotated, and the pictures will be presented. insuccession to the eye; but when the shaft ll has made one completerevolution the latchpin N strikes the arm m, lifting the latch-hook Mand freeing the bolt K, which, by virtue of the spring L, 'will be drawnback, and the end K will engage again with the projection 71 and theapparatus will be relocked.

O is a drawer to receive the coins.

It is evident in this construction that the springs L might be replacedby a weighted lever, as shown in dotted lines in Fig. (i.

The number of pictures presented to the eye upon each revolution of theshaft Il may of course be varied by changing the relative sizes of thespur-gears G, as illustrated in Figs. 2 and 7.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. A rotating shaft having a projection, a tube or coin-passage, a boltto normally hold said projection and shaft from rotating, said boltextending or projecting into the tube in the path of the coin, wherebythe coin in pass ing `through the tube moves said bolt and releases theshaft, allowing it to be rotated, a latch to hold said bolt away fromthe shaft projection, and a second projection carried by the shaft totrip the latch and release the bolt.
